View Full Version : Tetrachord discovery?

If you take the last major in the first tetrachord, and make it the first note in a tetrachord (while the first major becomes the first note in the 2nd tetrachord), then you take the 3rd minor in the new 2nd tetrachord, you then expand it into its scale. Then you plug it in as a jazz melodic minor and basically create a 9 note scale (including the octave). You also can theoretically make it a 19 note scale due to the fact that all the notes can arguable be in the same scale. This may not make much sense in writing, maybe i'll scan some drawing to help explain it, its really fascinating though...if you understand it, or if im incorrect...let me know what you think...heres a link to the pic that i drew out...

it may just be "borrowing" notes from other scales...but in theory it makes a huge scale

Do you mean its like a scale over 2 octaves???

you obviously know nothing about music theory Kalmahswamp because I won first place in the Division 3 championships of music theory.

Just fucking with you...i wish i could properly respond and help you.

Maybe I could write something cool if i knew how to read that:scatter::rolleyes::o.
But to answer Cloaca, most "fucked up" scales require 2 octaves to sort of fix itself out. For example, the A whole tone scale....

haha sorry...it is pretty sloppy...maybe i should draw up another one

the picture is more confusing than the text. and thats saying a lot

Its just a little tetrachord theory...if youre rusty on them, it may be a little confusing, i think the text is pretty clear, but i'll admit the drawing is kind of sloppy

i have no fucking clue what a tetrachord is

I have no idea eather. Can some of you theory buffs explain?

Very very interesting idea dude, I learned about Tetrachords and combining them to make the major scale, etc about a week and a half ago in my guitar class - The only problem I can see with this is that it looks to me that the tonal center is changing (key) from the major (A), to minor (F #), and finally to jazz melodic minor (C#). I'm not sure if this would end up sounding 'right', but I bet it has a unique sound to it. I haven't learned the fretboard quite well enough yet to be able to play that scale without putting a whole lot of thought into it - perhaps you could tab out what the resulting scale is from that?

I thought that you could combine your scales anyway. I mean like one specific scale, like the C Major obviously has more than one position and when I improvise I don't limit my self to one position of a scale.

Jesus christ, I don't think my brain could ever comprehend this stuff. I have the basics of music theory, but even that was a pain. Some of its just fucking BORING.

That diagram in the attachment scares me more than calculus

Haha, yeah, man. I understand logs (calc) and this shit is a pain in the ass! maybe if I knew what the hell a tetrachord was, I wouldn't be as confused.

Fuck off! I guarantee that you haven't seen ugly calculus until you've integrated paths and contours in the complex plane. Give me tetrachord theory any day.

I second that.

I thought this thread was dead. Anyway, Mansley, whats your take on my little theory?

Thats fucked up.Just plain old fucked up. but it works and you are correct. Its like synthetic Tetrachord jumbalaya. Thats what im gonna call your theory.

SYNTHETIC TETRACHORD JUMBALAYA.

I'm trying to invent a 15th chord with this mechanism :rofl:

Beyond 13th is impossible I believe.

what do you mean invent a 15th chord?

A 15th is an interval which is like the 7th but an octave higher if I'm not correct. I can't quite remember. I haven't had to go over an octave in quite a long time, with exception to a m9th, and 9th here and there.

Are there blues tetrachords?

[0-3-4-5]
[0-1-2-5]

These sound pretty bluesy to me, especially the former.

I showed this to a theory teacher at a school here and he was quite impressed, said it theoretically works.

But that 15th chord is impossible I think. Mansley...is it proven that a 13th is the highest you can get? Maybe if I had some other kind of instrument and another hand... :p

Surely it'd sound like shit anyway.
